6.1 General Check

CAUTION
·When clamping the wiring, use the included clamping material to prevent outside pressure being
exerted on the wiring connections and clamp firmly.
When doing the wiring, make sure the wiring is neat and does not cause the control box lid to stick up, then
·
close the cover firmly. When attaching the control lid, make sure you do not pinch any wires.
Outside the machine, separate the weak wiring(remote controller and transmission wiring) and strong
·
wiring(earth and power supply wiring) at least 50 mm so that they do not pass through the same place
together. Proximity may cause electrical interference, malfunction, and breakage.
WARNING
If the fuse blows, please call the service agency to replace it. Please do not replace it by yourself, or else
it may result in accident, for example, shock.
